About Converting Bits to Megabits
Bit and Megabit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: Bit digital storage unit, and megabit digital storage unit.
Formula
megabits = bits × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 bit equals 1 base unit, and 1 megabit equals 1000000 base units, so dividing one by the other gives the direct bit-to-megabit factor of 0.000001.
Simple example
1 bit × 0.000001 = 0.000001 Mb
1 bit = 0.000001 megabits.
Real-world example
500 bit × 0.000001 = 0.0005 Mb
500 bits = 0.0005 megabits.
Conversion table
| Bit (bit) | Megabit (Mb) |
|---|---|
| 1 bit | 0.000001 Mb |
| 8 bit | 0.000008 Mb |
| 16 bit | 0.000016 Mb |
| 64 bit | 0.000064 Mb |
| 256 bit | 0.000256 Mb |
| 1,000 bit | 0.001 Mb |
Reverse conversion: Megabit to Bit
0.000001 Mb × 1000000 = 1 bit
0.000001 megabits = 1 bit.
bits = megabits × 1000000

Understanding the Bit (bit)
Bit digital storage unit.
Understanding the Megabit
Megabit (Mb) measures digital storage/transfer. A megabit is 1,000,000 bits (125,000 bytes) under the decimal convention used for network speeds. It is classified as a Decimal (SI-prefixed) digital unit.
Where it's used: Used worldwide for network and internet speed ratings
Megabits vs. megabytes. Internet speeds are quoted in megabits per second (Mbps), while file sizes are quoted in megabytes (MB) — 8 megabits equal 1 megabyte, so a '100 Mbps' connection downloads at up to about 12.5 MB per second.
Uses of the Megabit today
- Internet connection speed advertising (Mbps)
- Network bandwidth measurement
History of the Megabit
Network speeds have conventionally been quoted in bits rather than bytes since early telecommunications measured signal rate in bits per second; this convention carried into modern internet service marketing, which is why connection speeds (Mbps) and file sizes (MB) use different base units, a frequent source of consumer confusion.
Historical origin. Megabit was not the invention of a single named person; it developed through the process described above.
Megabit — sources
- IEC 80000-13 — Defines bit-based units distinct from byte-based units.

Frequently asked questions
How many megabits are in 1 bit?
1 bit equals 0.000001 megabits, using the exact defined conversion factor rather than an estimate.
How do I convert bit to megabit?
Multiply the bit value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert megabit back to bit?
Use the reverse factor: 1 megabit equals 1,000,000 bits. You can also use the swap control in the converter above to flip the direction instantly.
What is a bit?
Bit (bit) is a unit of digital storage.
What is a megabit?
Megabit (Mb) measures digital storage/transfer. A megabit is 1,000,000 bits (125,000 bytes) under the decimal convention used for network speeds. It is classified as a Decimal (SI-prefixed) digital unit.
Is the bit to megabit conversion exact?
Yes. Both bit and megabit are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
What is the difference between megabits vs. megabytes?
Internet speeds are quoted in megabits per second (Mbps), while file sizes are quoted in megabytes (MB) — 8 megabits equal 1 megabyte, so a '100 Mbps' connection downloads at up to about 12.5 MB per second.
